SPECIFICATZGN forming part of Letters Patent No. 309,265, dated December16, 188-2.

Application filed September 3, 1884. (No model.)

To all whom it may concern.-

Be it known that we, FRIEDRICH Vnr'rnn and Hueo VETTER, both residentsof Brooklyn, in the county of Kings and State of New York, have inventeda new and Improved Gun-Lock, of which the following specification is afull, clear, and exact description.

This invention relates to various improvements in gun'locks adapted forbreech loading fowling-pieces and other guns,-and also to the mechanismfor securing the lock-case to the barrel.

The invention consists in the various elements of improvement,hereinafter more fully pointed out.

In the accompanying drawings, Figure l is a longitudinal section of ourimproved gun on the line as 00, Fig.3. Fig. 2 is a similar section, withthe barrels tilted, on the line y y, Fig. 3. Fig. 3 is a verticalcross-section on the line z .2", Fig. 1, and Fi 4 a top View of the armon the gun-case beneath the barrels.

The letter A represents the stock of a gun. B are the barrels, and C isthe lock-ease, made in one piece of metal and without any separate sideplates.

\Ve shall first describe the firing mechanism, and next the mechanismfor attaching and tilting the barrels so as to allow a new charge to beinserted.

a is the right and a theleft hammer. Each hammer is made in one piecewith the arbors These arbor-s are plainly shown in Fig. 3. The arbor bof the right hammer is made with a notch at its end, circular incross-section, into which fits a circular pin, Z), at the end of arborI) of the left hammer. In this way the arbors are free to turnindependently, and at the same time support themselves mutually. Uponeach arbor there is mounted a tumbler. Each tumbler is made of twopieces, placed side by side. The outer piece, a, is the tumbler proper,being connected to the mainspring (Z by a swivel in the ordinary manner.The inner piece or disk, 0, contains the usual cock-notches, which areengaged directly by the triggers f.

g are the trigger-springs for throwing the noses of the triggers intothe notches when the gun is cocked. The mainspring d is placed in frontof the hammer and secured by pin h to thelock-case. This springis madewith an upwardly-extending arm, 77, the end of which engages beneath anose, j, on the front of the tumbler c, forthrowing the hammer a slightdistance back after it has exploded the cap.

The operation of the gun as thus far described is as iollows: Either ofthe hammers a a, being drawn back, rotates its tumbler c and disk 0, soas to allow the nose of the trigger to be thrown into one of the notchesof the disk cby means of spring 9. The end of the mainspring (1 is ofcourse at the same time drawn up. The trigger f, when pressed, isdisengaged from the cock-notch, and the tumbler c is by spring (Zrevolved forward, carrying the hammer around with it. Immediately afterthe hammer has exploded the cap or cartridge the arm 1 of spring (1presses against the under side of nose j of tumbler c, and therebycauses the hammer to be thrown back to a slight ex tent, so that thereis always a small space between cap and hammer, even if the gun is notcocked.

The mechanism for securing the barrel B to the lock-case and forpermitting the tilting of the barrel is as follows: The case 0 isprovided beneath the barrel B with an arm, 7;, upon which the rearportion of the barrel rests. At its end the arm has a nose, Z, whichengages a notch of the barrel, and upon which the barrel is tilted. Thearm L is provided with two slots, into which fit two projectionsmz, ofthe barrel. These projections are notched at their rear edge, and thesenotches are engaged by a sliding bolt, a. This bolt can reciprocatelongitudinally in a longitudinal groove of arm 7.", and is normallythrown forward by a spring, 0. In this position it enters the notches ofthe projections m, thus properly holding the barrel in place.

For withdrawingthe bolt in order to tilt the barrel, the followingmechanism is employed: Through a perforation in the bottom plate of case0 extends a pin, 17, which passes through an eye at the end of bolt 01.The shank of the pin is surrounded beneath the bolt by aspiral spring, oTo one of the disks 0, preferably the right disk, there is pivoted anarm, 1', havin g a downward projection, s. This projection extendsdirectly in front of the end of pin z is a guide-rod, made in one piecewith arm r and sliding in a corresponding slot in case 0, to properlyguide the motion of arm 0". When the barrel B is to be tilted, the'pin pis pressed into the case by a finger. The pin passes through the eye inbolt 02 and enters behind the projection s of arm 1. Next the hammer aisrevolved back ward to a slight eXtent less than half-cock. This willcause the tumbler c and disk 6 to be revolved correspondingly, and thearm r is thereby swung backward, carrying the end of pin 1) with it. Inthis way the pin is oscillated and draws the bolt n out. As soon as theprojections m of the barrel are released the barrel will tilt 011 noseZ. After the barrel has tilted, the pin 12 and hammer are released. Thehammer will fly back into its original position, and the pin 1) will beforced down by its spring q. The rear edges of the projections m and thefront edges of the bolt n are beveled in opposite directions, Fig. 1, sothat as the barrel is leveled after being loaded the bolt willautomatically enter the notches in the projections m. The spring 0,throwing the bolt forward, will lock the barrel to the case as soon asthe bolt is opposite the notches in projections m.

We claim as our invention-- 1. The combination of hammer a, in one piecewith arbor b, with hammer a, in one piece with arbor b, the arbor I)having a notch circular in cross-section, and the arbor b a circularpin, 1), to engage said notch, substan- V tially as specified.

2. The combination of hammers a a, arbors b b, and tumblers 0, havingnoses j in front of tumblers,with mainsprings d, having arms 1; in frontof tumblers, and with notched disks 6, adapted to engage triggers f,substantially as specified.

8. In a breech-loading fire-arm, and in combination with thebarrel-locking bolt 92, the pin 19, passing through and looselysupported in the lock-case and engaging the bolt, the hammer-arbor Z),and the reciprocating arm 1", borne thereby, and engaging the pin 10when the latter is pressed inward, substantially as set forth.

4. In a breech-loading fire-arm, and in combination with thebarrel-locking bolt, the pin 19, loosely supported in the lock-case,through which it passes, and engaging the bolt, the hammer-arbor b,carrying the tumbler c and disk 0, and the reciprocating arm r,borne bythe latter, and engaging the inner end of the pin 19 when in its innerposition, to oscillate the same and unlock the barrels, substantially asset forth.

5. In a breech-loading fire-arm, and in combination with thebarrel-locking bolt, the pin p, loosely supported in the lock-ease andengaging the bolt, the pin-actuating spring, the reciprocating arm 1',operated by the hammerarbor and provided with a guide-rod, t, and thearm 1', engaging the pin 1) when pressed'inward, to oscillate the sameand thereby unlock the barrels, substantially as set forth.
